Title: Device for producing optical images having the form of data characters
IPC: G09F9/305
Filed: 1956-08-10
Abstract: 799,890. Optical systems. NATIONAL CASH REGISTER CO. Aug. 10, 1956 [Sept. 6, 1955], No. 24517/56. Class 97(1) [Also in Group XXXVIII] A device for producing optical images having the form of data characters comprises an assembly of light-conductive rods arranged substantially parallel with one another and having compartments formed within the assembly each provided with illuminating means, the walls of said compartments being provided with transparencies and opacities so as to form a lightdirective pattern in order that light from selected illuminating means will be transmitted only along predetermined lightconductive rods whereby each data character appears selectively as an optical image composed of a mosaic of illuminated areas on the end-face of the assembly. In the embodiment described fifteen light-transmissive plastic rods, such as 19, are stacked as shown in five rows, each three rods wide. The centre rod of the second and fourth rows is only a short length thereby leaving two openings extending through the remainder of the length of the stack. The inner edges of the rods surrounding these openings are chamfered (Figs. 3 and 4, not shown) and extend the openings into two channels of X shaped cross-section (Fig. 8, not shown). An assembly of ten X shaped opaque shields 36 rigidly spaced by stiff wires connected to the corners of each shield (Figs, 6 and 7, not shown) is inserted in each of the X shaped openings to divide the stack of rods into ten compartments such as C-1, C-O, C-8 &c. The shields 36 are preferably made of insulating material and each has an electric lamp 46 mounted thereon, the connections thereto being effected via the stiff wires positioning the shields 36 such that any one of the ten lamps in an assembly may be selectively lit. Each section C-1, C-0, C-8, &c. of the stacked rods thus has two lamps associated with it, one vertically above the other, and these pairs are wired in series or parallel so as to light together. Light from any of the lamps would pass along the rods by total internal reflection and illuminate all the end-faces, but in each compartment C-1, C-0, C-8, &c. the inner surfaces of selected rods are rendered opaque (Fig. 8, not shown) such that only certain of the rods receive light when any particular pair of lamps is lit. By this means digits from 1 to 9 and 0 are built up (Fig. 2 not shown). The digit 1 is the only one requiring the central rods of rows two and four to be illuminated and this allows these rods to be short as described; the first lamps (compartment C-1) being those selected when digit 1 is to appear. Several assemblies may be mounted together to provide a multi-stage register as in Fig. 1 (not shown).

Title: Electronic computer
IPC: G06F7/52
Filed: 1958-07-30
Abstract: 869,703. Digital electric calculating apparatus. SPINGIES, E., and ROSE, H. July 30, 1958 [Aug. 3, 1957], No. 24531/58. Class 106 (1). An electronic computer employing counting circuits includes an impulse transmitter consisting of several series - connected impulseretarded univibrators. As described, the computer comprises an input control 11, Fig. 1, including relay circuits for directing valuerepresenting pulses to stepby-step switching mechanism 12 which registers a 10-digit decimal number. The mechanism may be remotely-controlled and comprises two sets of five switches each including a wiper contact arm 24, Fig. 4, which is set to a position corresponding to the digit value. The seriesconnected univibrators 23<SP>1</SP>-23<SP>9</SP> of the pulse transmitter 13 supply a succession of pulses to diodes such as 35 of a decoupling network, the connections being such that 1-9 pulses respectively are supplied to the fixed contacts corresponding to 1-9 in all the ten switches. A number of pulses corresponding to each registered digit is therefore passed via denomination-shift diode network 14 to totalizer 16 which comprises ten C.R.T. decimal counting tubes. The totalizer switching and carry circuits 15 and 17 may be set for positive or negative counting under control of relays in circuit 11. Addition or subtraction of a number set up on mechanism 12 may thus be effected by applying a starting impulse to transmitter stage 23<SP>1</SP>. Reference is made to a key-controlled input, and to photo-electric means for supplying the computed data to other computing-machines. The duodecimal system may be used. Multiplication.-A 5-digit multiplicand is entered into the upper half, Fig. 4, of the switching mechanism, and a 5-digit multiplier into the lower half which is isolated from the totalizer by energizing relay 52. Multiplication is effected by repeated addition with denominational shift, a number of impulses corresponding to the value of each multiplier digit being applied to stage 231. Division.-This employs additional circuits including control circuit 18 which removes inhibition from transmitter univibrator 23<SP>10</SP> whereby the univibrators are ring-connected, and quotient counter 21 with associated denomination-shift, switching and carry circuits 19, 20 and 22, respectively. The dividend is in totalizer 16 and the divisor is entered in the upper half of the switching mechanism. Division is effected by repeated subtraction of the divisor, a " 1 "-representing pulse being applied from stage 23<SP>10</SP> over lead 48 to the quotient counter at the end of each cycle of the transmitter. When the highest denomination of the totalizer passes from " 0 to " 9 ", the divisor is added back and " 1 is subtracted from the quotient. A denomination shift is then effected in circuits 14 and 19, and the operations are repeated until a 5-digit quotient has been obtained. It is stated that the quotient counter may be part of the totalizer 16.

Abstract: 338,866. Waddington, A. S. Aug. 16, 1929. No Patent granted (Sealing fee not paid). Taximeters; mixed time and distance drive; with recording devices.-The taximeter spindle i is driven by distance from the vehicle wheels through the shaft d' and toothed wheels d<2> - - d<5> connected by a one-way clutch to shaft c and wheels d' and d<8>, and is driven by time from the clockwork drum b<1> through the toothed wheels t<1> - - t<5>, the last of which is connected to the shaft i by a one-way clutch. Loss of drive to the taximeter spindle i due to back-lash on changing over from one drive to another is prevented by connecting the time and distance drives by a yieldable coupling so that each drive tends to drive the other in the opposite direction. This coupling consists of a shaft b on which is fixed a collar c<2>, a pinion d engaging with the toothed wheel t<5>, the loose pinion d<6> engaging with the toothed wheel d<5>, and the compressed spring e which forces the pinion d<6> against the collar c<2> to provide a frictional drive between the time and distance drives. In an alternative construction the pinions d, d<6> are mounted separately. The Provisional Specification describes a modification in which a pinion driven by the distance gear train is connected fast to one end of a coiled spring under compression whose other end carries a flat disc contacting with the face of a pinion driven by the time gear train.

Filed: 1948-09-27
Abstract: 655,441. Controlling change-speed gearing. HUMBER, Ltd., and KAMPER, A. M. Sept. 27, 1948, No. 25188. '[Class 80(ii)] In a motor-vehicle gear box, first, second and reverse gears are brought in manually by angular movements of a gear lever XX from the full-line position shown, via arm 15 and fork 14. Third speed is brought in by a reversible electric motor II when the lever XX is moved axially to disengage from the fork 14 and engage a slide 16 and is then turned into the dotted line position shown so as to move the slide 16 and thereby operate a four-pole double-throw switch VI. The latter acts to close a circuit, via a contact strip IX coacting with one of a number of studs on an arm III, which engages a fork 17 controlling third and fourth speeds and which is geared to the motor II through epicyclic gearing IIc including a reaction member controlled by an electromagnetic brake IV, whereby, through relays, the main clutch I is disengaged, the brake IV is engaged so as to render the gear IIc operative to drive the arm III from the motor II, and the motor II is rotated forwardly to engage third gear. As the gear engages, the stud moves off the strip IX, causing the motor circuit to be broken, the brake IV to be released so as to free arm III from the motor, and the clutch I to be re-engaged. Fourth speed may now be brought in by pressing a button (not shown) which energizes a solenoid to turn a rotary switch so as to close a circuit via a contract strip X whereby, through relays, the clutch I is disengaged, the brake IV, is engaged, and the motor II is driven reversely to engage fourth gear. On engagement, the stud moves off the strip X and, as before, the motor is de-energized, brake IV is released and clutch I is re-engaged. On again pressing the button, the solenoid acts to open the rotary switch, and through the contact strip IX, third gear is re-established, the clutch I being disengaged during the change. If, with third (or fourth) gear engaged, the lever XX is moved to neutral position so as to restore the switch VI to normal position, a circuit is closed through a further contact strip (XII in the case of fourth gear), whereby, through relays, the clutch I is disengaged and the arm III is brought to neutral position, the stud moving off the strip to de-energize the motor, release the brake IV and re-engage the clutch I. Simultaneously, in moving the lever XX to neutral position when fourth gear is engaged, the switch VI operates to energize the solenoil through a contact strip XIII, whereby the rotary switch is. opened, to ensure that when the lever XX is next turned into the dotted line position, only third gear can engage. The pivoted knob XXA of the lexer X houses a switch which, when the knob is grasped to tilt the lever in either direction to engage a gear, acts to disengage the clutch I. Specifications 594,906, 610,519, 610,593, 610,595, 619,223, 632,028 and 635,792, are referred to.
